Batch image converter (most important .psd to .jpeg for web)

This converter can take virtually any number of images in any format (most importantly psd) and convert them within seconds to any of the most popular formats (most importantly jpg). The file converter will also resize, rotate, flip, mirror, crop individual or bulk images within seconds, as needed. I should also be able apply watermarks and any other effects you can think of. Should be able to compress the High res to different qualities depending on "image quality" parameter. Use a drop down slider or radio button to specify a value from 25% to 100%. 100% quality preserves original image quality.
